2.1 System Overview
The Honeywell VC4™ system continuously monitors up to 4 remote locations for toxic gases. It
responds to gases that exceed programmed levels by:
Triggering alarms and opening event windows to warn operators of high concentrations
l
Displaying the location, gas type and gas concentration
l
Storing the alarm information in a database
l
The VC4™ system provides fast response to a wide range of gases. Each location may be up to
400 ft (122 m) from the VC4™ system. The system triggers relays for each individual point for
two levels of gas concentrations.
The VC4™ system's flexibility allows it to be easily configured for tabletop use or rack mounting.
The VC4™ system uses Honeywell patented Chemcassette™ technology for rapid, accurate gas
detection. The system was designed for maximum uptime, so filters, Chemcassette™, and even
the entire chassis can be replaced quickly and easily. The system powers up in the same state
as when powered down.
Operation can be through an LCD touch screen or through a local area network (LAN).
Chemcassette™ is a registered trademark of Honeywell.
